Science properly correcting itself: The handling of alleged misconduct in claims by Paolo Macchiarini

According to a recent investigation, surgeon Paolo Macchiarini from the Karolinska Institute in Stockholm has allegedly committed scientific misconduct in his reporting of results from patient transplants of synthetic tracheas seeded with stem cells. The misconduct investigation 39-page report drafted by Bengt Gerdin, a professor at Uppsala University, reveals that in six published papers, author Paolo Macchiarini had deliberately and knowingly misrepresented or falsified medical data from recipients of the artificial tracheas. The papers allegedly boosted the results of the transplant operations making them appear far more more successful than they really were. The investigation also found that two of the papers described procedures that did not get ethical approval (Lancet 378, 1997–2004 (2011) and Biomaterials 34, 4057–4067; 2013), and that a seventh paper by Macchiarini (Nature Commun. 5, 3562; 2014) also contained fraudulent results.

The investigation launched by the Karolinska Institute began after four physicians at the institution, who were involved in the care of  Macchiarini’s transplant patients, filed formal complaints. The physicians identified themselves as Karl-Henrik Grinnemo, Matthias Corbascio, Thomas Fux and Oscar Simonson and provided medical records that are at odds with the results published by Macchiarini.

Irrespective of the validity of the misconduct findings by Bengt Gerdin, there seems to be at least one fundamental difference between this investigation and the ones prompted by the intrigues and attacks launched by PubPeer-Retraction Watch-Clare Francis contributors. In the Macchiarini case the accusers revealed their identities and proved that they were peers of the person they were accusing. In other words, they behaved as honest people would do and followed the standard course of action that science has developed to handle allegations of scientific misconduct. In addition, the procedure followed by the Karolinska Institute is the one that science has always accepted and has been in place for centuries, since the inception of scientific reporting.

By contrast, the feeders of the PubPeer-Retraction Watch-Clare Francis ring live in a world where you just sit on the outside of science and, while hiding in anonymity, take shots at those doing the actual work. Who the heck are these people at Retraction Watch and PubPeer anyway? Whose peers are they? These abominable practices must come to an end, but that will only happen when people realize that there is a fundamental difference between the way the Swedish Karolinska Institut reacted upon the allegations of four Macchiarini peers and the way amateurish editors handle the accusations by Clare Francis.
